The first issue facing any powered-lift vehicle is its specific lift capability; i.e., how many pounds it can lift per horsepower. Historically, lift system weights (power plant, drive train, rotors, ducts and nozzles) have severely limited the vehicle's ability to lift anything but itself.  We have successfully designed, developed and tested a combination of power plant, drive train and ducted fans, which are able to deliver significantly more thrust than the combined package weight, the result of these test has developed into our "Core Technology" which we have applied to the following machines:

OVIWUN Unmanned Air Vehicle (UAV)

Twin shrouded-prop, electric, mini-UAV. Based on the core technology used in our larger Springtail and Dragonfly models, OVIWUN can be flown in much tighter spaces.  Weighing less than four pounds, with batteries, this vehicle is operated by a line-of-sight seven channel radio.

SoloTrek and Springtail Exoskeleton Flying Vehicle (EFV)

Solo Trek was where it all started.  Our original, twin shrouded-prop, single engine, single seat, personal air vehicle.  First tethered flight - 12/18/2001.   Can be seen at the Hiller Flight Museum in San Mateo, CA.

The Springtail, redesigned and improved.  Twin shrouded-prop, powered-lift, single engine, single seat, personal air vehicle.  First tethered flight -  10/2/2003.  First free flight - 10/20/2003.  Retired - 3/16/2005.  Longest demonstrated flight time – 1.3 hr

Dragonfly Unmanned, Manned or Remote (UMR) Vehicle

Twin shrouded-prop, powered-lift, single engine, enclosed single seat, personal air vehicle.

This vehicle was initially designed as an unmanned utility cargo vehicle with over forty-one cubic feet of capacity, however it would beequally capable of manned or remote operation. The powered-lift VTOL configuration makes this vehicle extremely maneuverable and agile.

Answers to Frequently Asked Questions (FAQs)



The benefit of ducted fans are that they can be flown in tight spaces without worrying about running into things and damaging the blades/aircraft or the items it runs into.  This is perfect for flying in cramped quarters, below the tree line, or other tight situations.



OVIWUN can be flown both indoors and outside.



Springtail and Dragonfly both run on ONE rotary engine.  In the future different engines could be applied, however we do not have plans to do so at this time.

   4.. We currently fly the Springtail using 100 octane aviation gasoline, however the rotary engine used in the Springtail and Dragonfly vehicles is designed to use gasoline, diesel, or heavy (jet) fuel.  


The Springtail Vertical Take-off and Landing (VTOL) footprint is approximately the size of a picnic table.



Dragonfly is currently configured to carry one to two people, with an estimated capacity of 450 pounds.  


Springtail and Dragonfly blades are very quiet,  however the engine will need a better muffler, as it is quite loud!



Springtail and Dragonfly vehicles both have a range of about 2-3 hours with a ceiling of over 10,000 feet.



Springtail and Dragonfly are both designed to be equipped with a ballistic parachute in case of an emergency.  The operator can also wear a parachute as well.

  10. Since we are focusing on our consulting capabilities, the Springtail, Dragonfly, and Baja Skimmer vehicles are no longer for sale. However, if you are interested in an OVIWUN contact us to get on a waiting list.
